Liberty is a lovely soft darker blue. It would be wonderful for primitive style rugs and nice in a patriotic themed rug. I suggest Christmas Red (Issue 1 Wool Club Sample), Ruby Joy or Country Red for the red and for the "white" either Mr. Mr. Snowman or Neutral City. Liberty Blue is lovely with those from the Orange, Yellow Orange and Orange Yellows and the Greens from Chartreuse, Yellow Green, Spring Green and Green. For a nice gold try Gold Bullion or Sun Worshipping (Issue 1 Wool Club Sample).
Would be a nice background and would blend well with Ocean Deep (Turquoise 9). Dark Liberty Blue changes to Blue 11-16 with the addition of Black.. Mix the two together in a background for wonderful movement.
